How to avoid water streaks on the back window of a Tesla

Method 1: Use a soak rope and make sure to thoroughly insert it as tightly as possible. After a clean squeegee job, leave the soak rope in for a few minutes. If you pull out the soak rope right after squeegeeing, the rope will slide against your film and this is what causes the streaks. You can also just try using a little less water to minimize spillage and moisture. Some useful tools in this process are a bulldozer, a titan, a tri edge reach, and a thin microfibre towel.
